Abstract

Three-color photoelectric observations of eclipsing binary X Tri have been carried out in 1969-1972 in Abastumani astrophysical observatory (Table 1). On the basis of these observations corrected elements (1) were obtained which further were applied for the mean light curves calculations. The mean light curvs rectification followed Russell-Marrill technique. Photometric elements were calculated according to the programme by Lavrov's direct method. The elements thus obtained appear in Table 4. The absolute parameters derived in yellow light appear in Table 5. The model constructed (Fig.10) exhibits that the subgiant component fills its Roche lobe. Thus the X Tri proves an example of a typical semi-detached system, the cool component of which is losing its mass.
